This invention relates Ito a hair cutting apparatus having at least one blade held within a frame and more particularly, to a one piece hair trimmer in which the blade is easily adjusted and replaced and which trimmer enables the user to perform a variety of operations in combing and cut-ting of the hair.

Accordingly, it is an object of the present invention to provide a one piece hair cutter suitable for a variety of operations in a simple and easy manner.

A further object of the present invention is to provide a hair cutting apparatus which can cut hair as well as shave and in which the blade can quickly and Safely be replaced when desired.

A still further object of the present invention is to provide a hair cutting apparatus which can vary the cutting depth of the blade to perform a variety of cutting, shaving and trimming operations.

Another object of the presen-t invention is to provide a hair trimmer which is simple and safe in operation and easy and inexpensive to fabricate.

Further features and objectives of the invention will appear from the following description taken in conjunction with the accompanying drawings, wherein like numerals refer to like parts throughout, and in which:

FIGURE l is an enlarged top plan view of one embodiment ofthe present invention;

FIGURE 2 is an enlarged cross-sectional view taken along line 2-2 of FIGURE l;

FIGURE 3 is an enlarged cross-sectional view taken along line 3 3 of FIGURE 2;

FIGURE 4 is a top plan view of a fur-ther embodiment of the present invention; and

FIGURE 5 is a cross-sectional end view of the embodiment shown in FIGURE 4.

One embodiment of the present invention is shown in FIGURES 1-3 in which a one-piece hair trimmer 70 has a handle 72 at one end and a comb and cutter head 74 at its opposite end. Head 74 has a comb '76 along one edge and a hair cutter 78 along its opposite edge.

Hair cutter 78 has ya longitudinally extending recessed slot 80 adjacent the edge opposite comb 76. Slot S0 has a face 82. A plate or guide member 84 slidably mates with slot 80 and has a face S6 which abuts face 82. Faces S2 and 86 are urged together by the wedging action of a pair of latch arms 8S having overhanging ends. Latch arms 88, which are integral with head 74, project into corresponding openings 90 in plate 84. Adjacent and communieating with each of openings 90` in plate 84 at their ends remote from handle 72, is a groove 92. Groove 92 has a depression 94 at its end which cooperates with a lu-g 96 on the end of its corresponding latch arm S8, to urge plate 84 toward face 82. By relatively displacing plate 84 in the direction of arrow 98, latch arms 83 are flexibly urged over corresponding grooves 92 into depression 94.

Patented May 2S, 1968 'ice To aid in holding plate 84 in position, plate 84 has a finger 93 longitudinally extending toward handle 72 which is received in a slot 9S in head 74. A blade 100 has a pair of apertures 102 and 104 respectively seated about latch arms 8S to be properly set in position. Head 74 has :a row of comb teeth 106 along one side of the cutting edge of blade 100. Plate 84 has a downwardly taperede edge 108 along the cutting edge of blade 100, as shown in FIG- URE 3. To aid in moving plate 84 into and out of engagement with latch arms 88, a finger depression 110 is located on the outer surface of plate 84.

In cutting or trimming hair with the embodiment shown in FIGURES l and 2, the cutter head '74 is normally held at an acute angle to the hair being cut or trimmed and moved in the direction of the hair growth. The outer surface of teeth 106 is curved as indicated and rounded to avoid scratching the scalp or skin of the user. If a closer cut is desired, the beveled or tapered edge of plate 84 engages the skin of the user, and if a longer cut is desired, teeth 106 engages the skin or hair of the user.

A further embodiment is shown in FIGURES 4 and 5 in which a conventional straight razor blade is used in a holder which can vary the desired degree of cut or trim obtained.

As shown in the drawings, a blade holder 110 holds a single edge replaceable blade 112. Blade 112 is maintained in the desired position within holder 110 by a pair of screws 114 and a screw 120. Rotating screws 1'14 forces the ends of the screws into engagement with blade 112 as shown in FIGURE 5. Screws 114 force blade 112 against a plate 116 of holder 110. The remote e-dge of plate 116 has a row of teeth 118, which extend beyond the cutting edge of blade 112. To position blade 112 with respect to teeth 118 so as to obtain the desired depth of cut, bolt `120 can be adjusted to position the cutting edge of blade 112 with respect to the edge of teeth 118.

Advantageously, the bodies of the various embodiments are made unitary, and preferably are made of a plastic material, such as polypropylene to maintain stability and rigidity as well as being able to be exed without impairment or breakage. Since the cutters must be sterilized or cleaned often if used on different persons, the material must be able to withstand high temperatures and water.

While various forms of latches have been shown, another type is a resilient plastic button integrally attached to the body of the hair cutter assembly and positioned so that the iinger is yieldably urged past the resilient head and the plates are held in clamped position but could be released by iiexing the head.

The construction described permits the selection of cutting depths dependent upon the position of the cutter blade and the projection of .the comb teeth beyond the edge of the plate. The device shown may be easily and safely used by the user or by another.

As shown, the handle of the device serves the normal functions of the handle for the head of the cutter device, and also may be utilized to assist in holding the hair and forming a roll or curl therein.

From the above description, it is seen that the present invention has provided a novel device which may be relatively easily and economically manufactured and used. Since numerous lmodifications and changes will readily occur to those skilled in the art, it is not desired to limi-t `the invention to the exact construction and operation shown and described, and accordingly all suitable modiications and equivalents may be resorted to, falling within the scope of invention as claimed:

What is claimed is:

1. Hair comb with hair cutter, comprising a head, a razor blade and a handle integrally projecting longitudinally from one end of said head, said head having 1a recess in one surface longitudinally extending from the other end adjacent one longitudinal edge for receiving said razor blade, a latch arm integrally attached to and extending transversely from the bottom surface of said recess and having an overhanging end axially aligned with the longitudinal axis of said recess, said overhanging end having a protuberance extending .toward said recess, a guide member having an opening extending transversely therethrough to receive said latch arm, said guide member having substantially the length and width of said recess so as to be received therein and having a height substantially equal -to the height of the undersurface of said overhanging end of said latch arm, so that said latch arm en gages the top portion of the wall about the opening in the guide member, said top wall portion of said guide member having a recess for receiving said protuberance on said latch arm, whereby Said guide member is locked in said recess of said head `when in operative position, said guide member being downwardly tapered alonge one longitudinal edge corresponding to said one edge of said head, said head having a row of teeth extending transversely from said one and the other longitudinal edges, said razor blade adapted to be received by said latch arm when positioned in said recess between said head and said guide member, whereby said blade is clamped in hair cutting position in said recess along said one longitudinal edge by said latching arm `forcing said guide member into locking position with said head.

2. A hair comb as defined in claim 1, wherein said guide member has -a depression in the top surface adjacent said one end, adapted to receive a finger of the user for operatively moving said guide member.

3. A hair comb as defined in claim 1, wherein said head has a longitudinally extending opening in said one end and facing said guide member receiving recess and said guide member having a finger longitudinally extending from said one end adapted to be received by said opening when said Vguide member is locked in operative position in said recess.
